Dr. Mark Gilbert on Genetics as a Predictive Tool for Treatment Response in Brain Cancer

Mark Gilbert, MD, neuro-oncologist, chief of neuro-oncology, National Institute of Health, discusses predicting how a patient's brain tumor might act and respond to treatment based on their genetics. Gilbert says one way an oncologist might be able to predict these factors is looking at a patient's nucleotides in their DNA. He says these polymorphisms can reveal different types of enzyme activity, which in turn can potentially allow oncologists to guess more accurately at how a treatment might impact a patient.
